6 Claims. (Cl. 20-53) This invention relates in general to new and useful improvements in window construction, and more specifically to an improved window construction of the type which swings about a horizontal pivot.

One of the more expensive items of a window construction is an operating mechanism which will both operate a window and move. it between an opened and a closed position and retain it in the opened position. This is particularly true where the windows are positioned in high places in walls and not readily accessible.

It is therefore the primary object of this invention to provide an improved window construction of the type which swings about a horizontal pivot, the window construction including a sash frame having hollow vertical frame members in which there are disposed weights whereby as the sash is tipped from a vertical position to a partially inverted sloping position, the weights within the hollow frame members will slide from the original lower end of the frame members to the original end of the frame members so as to retain the sash in its open position.

nited States Patent Another object of this invention is to provide an improved window construction of theltype which swings about a horizontal pivot, the window construction includ- I ing a sash frame which is formed of hollow members ice ing two of the window constructions of Figure 1 in use for the purpose of ventilating a building;

Figure 3 is an enlarged vertical sectional view taken substantially upon the plane indicated by the section line 33 of Figure l and shows further the details of the window construction, the sash being illustrated in a closed position; and

Figure 4 is an enlarged fragmentary vertical sectional view similar to Figure 3 and shows the sash in an open position, portions of the window frame and sash being broken away.

Referring now to the drawings in detail, it will be seen that there is illustrated in Figures 1, 3 and 4 a window construction in accordance with the present invention, the window construction being referred to in general by the reference numeral 10. The window construction 10 includes a window frame which is referred to in general by the reference numeral 12. The window frame 12 is of a conventional construction and includes a header 14, a sill 16 and a pair of jambs 18.

Mounted within the window frame 12 for pivoting about a horizontal axis is a sash which is referred to in general by the reference numeral 20. The sash 20 includes a sash frame 22 which is of a size to fill the opening of the window frame 12. The sash frame 22 has positioned therein a pane 24. The sash frame 22 includes an upper frame member 26, a lower frame member 28 and vertical frame members 30. Coaxial horizontal pivots 32 extend between the vertical frame members 30 and the jambs 18 to pivotally mount the sash frame 22 within the window frame 12.

In order to provide an effective seal between the sash 20 and the window frame 12, the header 14 is provided with a downwardly projecting inverted T-shaped rib 34 which is engaged by a suitable Weatherstripping 36 carried 'by the upper frame member 26. The sill 16 is of a similar construction and'includes a T-shaped rib 38 which projects upwardlytherefrom and is engaged by a Weatherstripping 40 carried by the lower frame member 28; Carried by the header 14 and positioned between the T-shaped rib 34 and the main part of the header 14 is an L-shaped flashing member 42 which eluding a window frame having mounted therein a sash,

the sash being mounted on coaxial pivots carried by the window frame below the vertical center of the sash whereby the sash may be swung from a vertical closed position through an angle in excess of 90 to a generally inverted sloping open position.

A further object of this invention is to provide an improved window construction for use in buildings, such as schools, in the upper parts of the walls thereof to control ventilation through the school, the window being so constructed whereby a sash thereof normally slopes downwardly and inwardly andis in an inverted position when open whereby the flow of air through the lower also functions as a stop to limit the outward swinging of the upper end of the sash 20. A similar L-shaped flashing 44 is carried by the sill 16 to limit inward swinging of the lower end of the sash 20. It is to be understood that suitable Weatherstripping will be disposed intermediate the jambs 18 and the vertical frame members 30.

As is best shown in Figures 3'and 4, the vertical frame members 30 are of a hollow constmction and normally disposed in the lower ends thereof are weights 46. The weights 46 are free to slide longitudinally of the lengths of the vertical frame members 30. When the sash 20 is'in'a closed position, as is illustrated in Figure 3,

the weights 46 are in the lower ends of the vertical frame members 30 in engagement with the lower frame member 28. Thus the weights 46 serve to hold the sash '20 in a vertical closed position.

In the opening of the window construction 10, the sash 20 has the upper end thereof swung inwardly and downwardly as shown by the arrows in Figure 4. The final open position of the sash 20 is illustrated in Figure 4. As the sash 20 swings about the pivot 32, the weights 46 reach overcenter positions and slide down through the vertical frame members 30 to the new lower ends thereof, which lower ends are the original upper ends, with the weight 46 engaging the upper frame member 26. Thus the weights 46 shift as the sash 20 is pivoted from a vertical closed position to an inverted tilted open position and the weights 46 serve to retain the sash 20 in this open position.

In order to both limit swinging of the sash 22 in an open position and to prevent rattling of the sash when in such an open position, there are provided stop means which are referred to in general by the reference numeral 48. The stop means 48 includes a clip 50 which is secured to each of the jambs 18 by means of a mounting block 52. Carried by each of the vertical frame members and projecting outwardly therefrom is a pin 54 which is interlockable with the clip 50 to retain the sash 29 in the position illustrated in Figure 4.

While two weights 46 have been illustrated and described and two stop means 48 have been illustrated and described, it is to be understood that these are not necessary and one of each will suffice. It is also pointed out that the pivots 32 are disposed below the vertical center of the sash 20 so that the sash 20 may swing within the window frame 12 clearing all components thereof.

Referring now to Figure 2 in particular, it will be seen that there is illustrated a practical application of the present invention. Illustrated is a building which is referred to in general by the reference numeral 56. The building 56 may be of any type, but'is generally to be considered as a school because of its design. The building 56 includes a pair of walls 58 and 60 having a relatively flat roof 62 extending therebetween. Disposed in the lower part of the individual walls 58 and 60 is'a window construction 64 which may either be of the fixed type for the purpose of providing light only or which may be open for ventilation purposes. Disposed in the upper part of each of the walls 58 and 60 is one of the window constructions 10. The sashes 20 of the window'constructions are illustrated in open position. Thus it will be seen that when there is a breeze from the right, as viewed in'Figure 2, air will enter into the building 56 beneath the sash 20 of the wall 60 and be directed downwardly into the building 62 and then upwardly and out through the window construction below the sash in the wall 58. Thus adequate ventilation of the building 56 is assured by the window construction 10 when placed in proper positions in the walls of the building.

The foregoing is considered as illustrative only of the principles of the invention. Further, since .numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
